I will await on Varitube's response and see what my options are....will keep anyone updated if they want.
Tell them that they should send you the replacement, prior to you sending them back the one you have. Offer to give them your credit card # which they can hold onto, without charging, and that you'll send your defective SX back to them within 3 days of receiving the replacement SX.
IF they don't get your device back within two weeks? three weeks?, they you pre-authorize them to go ahead and charge your cc for the 2nd device. if they get the defective one back in time (which they certainly would), then they're not at a loss....
Explain that you don't want to be without your SX, and this allows you to keep the one you now have, until they get the other one sent out. They shouldn't be in a hurry to get the defective one back, they just want to make sure they eventually get it back!
I'd then make sure to have a tracking #, or signature required, when you return the defective SX, to make sure that once you send it out, there are no mishaps.....
Other companies have allowed me to do this in similar situations...
